By deciding color data corresponding to given image data using a color data determining means, by providing a display pattern corresponding to the color data using a pattern recognizing means, by deciding gray scale data providing a specified shade of gray by giving frame rate control to the color data through a frame rate controlling means and by employing an Extension register provided within the pattern recognizing means, whether an intermediate gray shade is displayed or not is decided. Furthermore, by deciding color data corresponding to given image data using a color data determining means, by providing a display pattern corresponding to the color data using a pattern recognizing means and by deciding gray scale data providing a specified shade of gray by giving frame rate control to the color data through a frame rate controlling means and by employing an Extension register provided within the frame rate controlling means, whether an intermediate gray shade is displayed or not is decided.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A gray shade displaying device comprising: a color data determining means to determine color data corresponding to given image data; a pattern recognizing means to provide a display pattern corresponding to said color data and to decide shades of gray corresponding to color elements for RGB (red, green and blue) colors to which said determined color data belongs; and a frame rate controlling means having two or more gray shade registers to decide gray shade data providing a specified shade of gray by giving frame rate control to said color data and to decide a frame function to which each color element is allocated, whereby said frame rate controlling means has an extension register to decide whether an intermediate gray shade is displayed or thinned out in a current frame of said image data.
2. The gray shade displaying device according to claim 1 , further including N bits of gray shade registers each giving a different display pattern and wherein an intermediate gray shade is displayed in N shades of gray by using data contained in said gray shade register providing a higher shade of gray by one as one bit out of N bits of said gray shade registers.
3. A gray shade displaying device comprising: a color data determining means to determine color data corresponding to given image data; a pattern recognizing means to provide a display pattern corresponding to said color data and to decide shades of gray corresponding to color elements for RGB (red, green and blue) colors to which said determined color data belongs; and a frame rate controlling means to decide gray shade data providing a specified shade of gray by giving frame rate control to said color data and to decide a frame function to which each color element is allocated, whereby said frame rate controlling means has an extension register to decide whether an intermediate gray shade is displayed or not; wherein it is provided with N bits of gray shade registers each giving a different display pattern and wherein an intermediate gray shade is displayed in N shades of gray by using data contained in said gray shade register providing a higher shade of gray by one as one bit out of N bits of said gray shade registers; and wherein the AND of specified low order bits of said color data is computed and, when said ANDed value is zero (0), said color data is judged to be said intermediate gray shade.
4. A gray shade displaying device comprising: a color data determining means to determine color data corresponding to given image data; a pattern recognizing means to provide a display pattern corresponding to said color data and to decide shades of gray corresponding to color elements for RGB (red, green and blue) colors to which said determined color data belongs; and a frame rate controlling means having two or more gray shade registers to decide gray shade data providing a specified shade of gray by giving frame rate control to said color data and to decide a frame function to which each color element is allocated, whereby said frame rate controlling means has an extension register to decide whether an intermediate gray shade is displayed or thinned out in a current frame of said image data.
5. The gray shade displaying device according to claim 4 , further including N bits of gray shade registers each giving a different display pattern and wherein an intermediate gray shade is displayed in N shades of gray by using data contained in said gray shade register providing a higher shade of gray by one as one bit out of N bits of said gray shade registers.
6. A gray shade displaying device comprising: a color data determining means to determine color data corresponding to given image data; a pattern recognizing means to provide a display pattern corresponding to said color data and to decide shades of gray corresponding to color elements for RGB (red, green and blue) colors to which said determined color data belongs; and a frame rate controlling means to decide gray shade data providing a specified shade of gray by giving frame rate control to said color data and to decide a frame function to which each color element is allocated, whereby said frame rate controlling means has an extension register to decide whether an intermediate gray shade is displayed or not; wherein it is provided with N bits of gray shade registers each giving a different display pattern and wherein an intermediate gray shade is displayed in N shades of gray by using data contained in said gray shade register providing a higher shade of gray by one as one bit out of N bits of said gray shade registers; and wherein the AND of specified low order bits of said color data is computed and, when said ANDed value is zero (0), said color data is judged to be said intermediate gray shade.
7. A method of displaying gray shades comprising the steps of: deciding color data corresponding to given image data by using color data determining means; providing a display pattern corresponding to said color data by using pattern recognizing means; deciding gray shade data providing a specified shade of gray by giving frame rate control to said color data by using frame rate controlling means; and deciding whether an intermediate gray shade is displayed or thinned out by using extension register means provided within said frame rate controlling means.
8. The method of displaying gray shades according to claim 7 , further including N bits of gray shade registers each providing a different display pattern and wherein an intermediate gray shade is displayed in N shades of gray by using data of said gray shade register providing a higher shade of gray by one as one bit out of N bits of gray shade registers.
9. A method of displaying gray shades comprising the steps of: deciding color data corresponding to given image data by using said color data determining means; providing a display pattern corresponding to said color data by using said pattern recognizing means; deciding gray shade data providing a specified shade of gray by giving frame rate control to said color data by using frame rate controlling means; and deciding whether an intermediate gray shade is displayed or not by using said extension register provided within said frame rate controlling means; wherein it is provided with N gray shade registers each providing a different display pattern and wherein an intermediate gray shade is displayed in N shades of gray by using data of said gray shade register providing a higher shade of gray by one as one bit out of N bits of gray shade registers; and wherein the AND of specified low order bits of said color data is computed and, when said ANDed value is zero (0), said color data is judged to be said intermediate gray shade.
10. A method of displaying gray shades comprising the steps of: deciding color data corresponding to given image data by using color data determining means; providing a display pattern corresponding to said color data by using pattern recognizing means; deciding gray shade data providing a specified shade of gray by giving frame rate control to said color data by using frame rate controlling means; and deciding whether an intermediate gray shade is displayed or thinned out by using extension register means provided within said frame rate controlling means.
11. The method of displaying gray shades according to claim 10 , further including N bits of gray shade registers each providing a different display pattern and wherein an intermediate gray shade is displayed in N shades of gray by using data of said gray shade register providing a higher shade of gray by one as one bit out of N bits of gray shade registers.
